2.1.0 - A hybrid major/minor upgrade!

what's new?

• opacity is now here! utilize components that require opacity such as images, etc.
• the mouse rules are better and easily seen now
• we have a new help URL!
• cursors are now added in multiplayer! don't mind the "Dummy user" name, I am too lazy to change that
• NOW ADDED POLYGONS! make custom shapes with any setting you want!
• labels now support \n escape sequence
• you can now open the context menu! just right click on the canvas on any situation and get actions at your fingertips
• bug fixes and minor improvements

thanks to Hack Club's Summer of Making for my motivational support to continue on this version (2.1.0)
